A male coupling that is connectable to and separable from a female thread ed coupling (e.g., a female threaded port) is provided. The female threaded coupling includes a sealing surface and a receiving portion sized to receive at least a portion of the male coupling, where the receiving portion has in ternal threads provided therein. The male coupling includes a body having a passageway extending therethrough and a locking member (e.g., ratcheting or non- ratcheting) disposed about the body and configured to move between lock ing and releasing positions. The locking member has a retaining formation co nfigured to engage the internal threads of the female threaded coupling when the locking member is in its locking position. The male coupling also inclu des an axially movable sleeve disposed about the body and an annular seal di sposed about the sleeve. After insertion of the male coupling into the femal e threaded coupling, the retaining formation of the locking member engages o ne or more of the internal threads in the female threaded coupling when the locking member is in its locking position. Upon movement of the sleeve towar ds the female threaded coupling, the annular seal is compressed against the sealing surface of the female threaded coupling.
